AT&T’s integration team got to meet their prospective colleagues at Time Warner last week, sources tell On the Money.

The former Ma Bell has said it can achieve a billion dollars in corporate and procurements synergies over the next three years.

The integration team led by Lori Lee, AT&T’s executive vice president of global marketing, also includes Eric Simpson, the company’s chief of staff, and Michael Welch, AT&T AdWorks head of strategy, product and business development.

They’re likely to be focused on figuring out how to slash the two firms’ massive ad budgets, as well as what data the two companies can share to deliver more ad revenue to the top line.

AT&T Chief Financial Officer John Stephens said the two companies combined spend some $6 billion in advertising.

The Dallas-based firm has hired management consultants Deloitte to work on the vast integration process, which will also involve ways of delivering mobile phone viewing data to marketers.

Earlier this week, AT&T won approval for its get-together from the European Commission. Now it’s waiting on the Department of Justice, which is in turn waiting for President Trump’s appointment for FTC chief.
